In an endoscope flexible tube and an endoscope device of the present invention, an endoscope flexible tube which exhibits flexibility to be inserted into a body cavity includes a bending portion formed at a distal end side, a first flexible tube portion connected in series to a proximal end of the bending portion, and a second flexible tube portion connected in series to a proximal end of the first flexible tube portion. When the bending portion and the first flexible tube portion pass a flexed portion of the body cavity, a curvature radius of the first flexible tube portion which is passively bent under a predetermined force is set to be larger than a curvature radius of the bending portion in a maximum bent state.

A method of 3D holographic recording by using a very simple optical system includes dividing a femto-second laser pulse into a plurality of light beams by a diffraction beam splitter, focusing four light beams selected from the divided plurality of light beams, controlling each optical phase of the selected four light beams by a phase retarder, and further focusing these four light beams into a sample comprised of a photosensitive material capable of multi-photon exposure so that the photosensitive material is exposed to the interference among the four light beams and multi-photon absorption in the sample is induced, thus recording a 3D phase hologram on the irradiated portion of the sample.

In an electrodeless discharge lamp 1 comprising a bulb 10 into which discharge gas and mercury which is controlled at a temperature of a coldest spot are filled, a power coupler 20 generating high frequency electromagnetic field, and a ferrule 15 for coupling the bulb 10 and the power coupler 20, the bulb 10 is configured of a substantially spherical barrel 14 formed of a transparent material and having an opening, and a sealing member 11 welded to the opening of the barrel 14 and having a substantially cylindrical cavity 5; a protrusion 4, which becomes a coldest spot when the lamp is lit in a state that the ferrule 15 is disposed upward, is formed at an apex of the bulb 10; and a protruding portion 17 is formed in a vicinity of just above the ferrule 15 of the bulb 10, that is, in a bulb neck portion 19 so that the bulb neck portion 19 becomes the coldest spot when the lamp is lit in a state that the ferrule 15 is disposed downward. Thereby, a constant optical output is obtained regardless of a posture of installation of the electrodeless discharge lamp 1.

There is disclosed a method of prediction time-series continuous data in which the data is accurately predicted based on measuring points and measured values at the measuring points of the data. From past measuring points t0 to t3 before a prediction point t4, a closest measuring point t3 which is closest to the prediction point t4 is sampled. Past n measuring points before the closest measuring point t3 are also sampled. Subsequently, a predicted value Q4 is determined from an interpolation formula f(t), which can derive a measured value Q3 at the closest measuring point t3 from the closest measuring point t3, i.e., Q3=f(t3) which is prepared from the past n measuring points, the measured values, the prediction point t4 and the predicted value Q4. The method can be implemented in a controller.

An endoscope includes a flexible tube and a connection mouth ring. The flexible tube includes a helical tube, a braid tube disposed outside the helical tube, and an outer tube disposed outside the braid tube. The endoscope further includes a caulking member which caulks the end of the braid tube from the outside of the connection mouth ring in a state held therebetween. The end of the helical tube is connected by thermal action to the connection mouth ring, and a part where the end of the helical tube is connected to the connection mouth ring is positioned differently along the axis of the connection mouth ring from a part where the end of the braid tube is caulked against the connection mouth ring.

An electrodeless discharge lamp has a bulb into which a discharge gas and a mercury, which is controlled at a temperature of a coldest spot are filled. A power coupler generates a high frequency electromagnetic field. A ferrule couples the bulb and the power coupler. The bulb is configured as a substantially spherical barrel formed of a transparent material and has an opening. A sealing member is welded to the opening of the barrel having a substantially cylindrical cavity. A protrusion, which becomes the coldest spot when the lamp is lit in a state that the ferrule is disposed upward, is formed at an apex of the bulb. A protruding portion is formed in a vicinity just above the ferrule of the bulb, that is, in a bulb neck portion, so that the bulb neck portion becomes the coldest spot when the lamp is lit in a state that the ferrule is disposed downward. Thereby, a constant optical output is obtained, regardless of a posture of installation of the electrodeless discharge lamp.
